Dr Merchant referred to a study on "Elderly in India" undertaken by Central Statistics Office, Ministry of Statistics and Programme implementation, which shows that the elderly population as per Indian Census 2011 stood at 8.2 per cent.

The statistics indicated that the elderly population in the country is expected to touch 10.7 per cent of the population by 2021 and further rise to 12.4 per cent by 2026.

"In India, elderly population is growing due to better economic standards of living. This approach to treating cardiovascular disease offers a newer lease to life to elderly Indian population," Dr Merchant told PTI on the occasion of World Health Day which was observed early this week.

According to World Heart Federation, non-communicable diseases (NCDs), including Cardio Vascular Diseases (CVDs), account for 60 per cent of total adult deaths in India out of which CVDs account for over a quarter(26 per cent).

Dr M G Bhat, a noted Bariatric surgeon and Surgical Gastroenterology specialist from Bangalore, said, "Elderly patients suffering from co-morbid conditions are at a higher risk for anaesthesia and surgery. And if there are obese, the risks become higher."

"With weight reduction they make a dramatic improvement. Their mobility improves, the co-morbid conditions become better and overall there is improvement in the quality of life. I see a small 5 to 10 percentage of such patients, and depending on their general status some of them are advised bariatric surgery," Dr Bhat said.

Research has proven strong linkage of obesity and diabetes with Cardiac health, said senior diabetologist at 'Diabetes Relief', Dr Deepak Patil said.

Patients suffering from obesity and diabetes (which is prevalent in elderly patients) stand at a much greater risk of contracting cardio-vascular disease, he added.
